Marcia L. Stefanick, Ph.D.
Professor (Research) of Medicine (Stanford Prevention Research Center), of Obstetrics and Gynecology and, by courtesy, of Epidemiology and Population Health
Current Research and Scholarly InterestsMarcia L. Stefanick, Ph.D is a Professor of Medicine Professor of Obstetrics and Gynecology, and by courtesy, Professor of Epidemiology and Population Health at Stanford University School of Medicine. Dr. Stefanick’s research focuses on chronic disease prevention (particularly, heart disease, breast cancer, osteoporosis, and dementia) in both women and men. She is currently the Principal Investigator the Women’s Health Initiative (WHI) Extension Study, having been the PI of the Stanford Clinical Center of the landmark WHI Clinical Trials and Observational Study since 1994 and Chair of the WHI Steering and Executive Committees from 1998-2011, as well as PI of the WHI Strong and Healthy (WHISH) Trial which is testing the hypothesis that a DHHS-based physical activity intervention, being delivered to a multi-ethnic cohort of about 24,000 WHI participants across the U.S., aged 68-99 when the trial started in 2015, will reduce major cardiovascular events over 8 years, compared to an equal number of “usual activity” controls. Dr. Stefanick is also PI of the Osteoporotic Study of Men (MrOS) which is continuing to conduct clinical assessments of bone and body composition in survivors of an original cohort of nearly 6000 men aged 65 and over in 2001. As founding Director of the Stanford Women’s Health and Sex Differences in Medicine (WHSDM, “wisdom”) Center, she plays a major role in promoting research and teaching on Sex and Gender in Human Physiology and Disease, Women’s Health and Queer Health and Medicine. Dr. Stefanick also plays major leadership roles at the Stanford School of Medicine, including as co-leader of the Population Sciences Program of the Stanford Cancer Institute, Stanford’s NCI-funded comprehensive cancer center.
Dr. Stefanick obtained her B.A. in biology from the University of Pennsylvania, Philadelphia, PA (1974), then pursued her interest in hormone and sex difference research at the Oregon Regional Primate Research Center, after which she obtained her PhD in Physiology at Stanford University, focusing on reproductive physiology and neuroendocrinology, with exercise physiology as a secondary focus. Her commitment to human research led to a post-doctoral fellowship in Cardiovascular Disease Prevention at the Stanford Prevention Research Center, which has been her academic home for nearly 40 years. -

John Witte
Professor of Epidemiology and Population Health, of Biomedical Data Science and, by courtesy, of Genetics
BioDr. Witte joined the Stanford community in July 2021. In addition to serving as Vice Chair and professor in the Department of Epidemiology & Population Health, and as a professor of Biomedical Data Science and, by courtesy, of Genetics, he will also serve as a member of the Stanford Cancer Institute.
Dr. Witte is an internationally recognized expert in genetic epidemiology. His scholarly contributions include deciphering the genetic and environmental basis of prostate cancer and developing widely used methods for the genetic epidemiologic study of disease. His prostate cancer work has used comprehensive genome-wide studies of germline genetics, transcriptomics, and somatic genomics to successfully detect novel variants underlying the risk and aggressiveness of this common disease. A key aspect of this work has been distinguishing genetic factors that may drive increased prostate cancer risk and mortality among African American men. Providing an avenue to determine which men are more likely to be diagnosed with clinically relevant prostate cancer and require additional screening or specific treatment can help reduce disparities in disease prevalence and outcomes across populations. Dr. Witte has also developed novel hierarchical and polygenic risk score modeling for undertaking genetic epidemiology studies. These advances significantly improve our ability to detect disease-causing genes and to translate genetic epidemiologic findings into medical practice.
Dr. Witte has received the Leadership Award from the International Genetic Epidemiology Society (highest award), and the Stephen B. Hulley Award for Excellence in Teaching. His extensive teaching portfolio includes a series of courses in genetic and molecular epidemiology. He has mentored over 50 graduate students and postdoctoral fellows, serves on the executive committees of multiple graduate programs, and has directed a National Institutes of Health funded post-doctoral training program in genetic epidemiology for over 20 years. Recently appointed to the National Cancer Institute Board of Scientific Counselors, Dr. Witte has been continuously supported by the National Institutes of Health.
